[Solved]-Using D3 loaded with json file, How can get parent nodes value from json file?-d3.js

I changed child to children, of course, and have this fiddle. Is this what you want?

I have done nothing special except for the change above. The numbers coming from the different levels correspond to the tree depth, as can be seen in the corresponding text element:

.text(function(d) { return d.depth + ": " + d.size;});
